The French side is pretty straightforward. The date separates two symbols. Left is the Paris mint, right the sign of its director at the time, Lucien Bazor - he didn't design the coin, Henri Patey did. The hole was a consequence of the introduction of copper-nickel as a mint metal. The Cu-Ni coins were badly accepted until they were holed, to distinguish them from silver. On a zinc coin, the hole is useless, but this is a war-time issue. The previous issue was in a copper-nickel alloy, with some zinc added. Since copper and nickel are war metals, they were replaced by zinc, but otherwise, the coin remained practically unchanged.
The Tunisian side says in calligraphed Arabic script (top to bottom):
احمد
مدة
باي تونس
١٠
صنتيم
١٣٦٠
سنة
which means: Ahmad, regent of Tunis, 10 Centimes 1360 year
Peter
